Digital Visual Interface (DVI) cables are used to transmit high-quality video signals between devices like computers, monitors, and projectors. They are ideal for settings where high-resolution display is crucial, such as graphic design, gaming, and video editing.

No, DVI cables are designed exclusively for video transmission. If you need to transmit audio, you'll require a separate audio connection or consider an interface like HDMI that carries both audio and video.

Select a DVI cable based on the required connection type (DVI-D for digital signals, DVI-A for analog, or DVI-I for both), desired resolution, and cable length. Ensure compatibility with your devices' ports and the resolution they support.

Single link DVI cables support resolutions up to 1920x1200, while dual link DVI cables can handle higher resolutions up to 2560x1600. Choose a dual link cable for displays requiring higher resolutions or refresh rates.
